As an expert in the field of outdoor and travel gear, I have a deep understanding of the various materials and designs that go into creating backpacks suitable for different environments. When it comes to the topic of whether Kanken backpacks are waterproof, it's important to consider several factors including the materials used, the construction of the bag, and the specific features that contribute to its water resistance.

Firstly, the term "waterproof" is quite definitive and implies that the backpack can be submerged in water without any water getting inside. However, in the context of backpacks and many other products, this term is often used interchangeably with "water-resistant" or "water-repellent." Water-resistant materials can withstand light rain or splashes but are not designed to keep out water under pressure or when submerged. Water-repellent materials are treated to repel water to some extent but may not be completely impermeable.

Kanken backpacks, made by Fjällräven, are known for their durability and minimalist design. They are typically made from Vinylon F, a durable, tightly woven fabric that is both lightweight and strong. This material is treated to be water-repellent, which means it can handle light rain and prevent water from soaking into the fabric immediately. However, it is not fully waterproof in the sense that it cannot be submerged in water without the risk of water getting inside.

The construction of the backpack also plays a role in its water resistance. Kanken backpacks feature a roll-top closure, which can be tightened to prevent water from entering the main compartment. However, this closure is not airtight and is not designed to keep out water under pressure. Additionally, the zippers and seams are not necessarily waterproof, which means that water can potentially seep in through these areas if the backpack is exposed to heavy rain or if it is submerged.

It's also worth noting that even backpacks made with waterproof materials are not always fully waterproof. The zippers, seams, and other components can still allow water to enter if they are not properly sealed or treated. For example, a fabric may be waterproof, but if the zipper is not, water can still get in through the zipper. Similarly, the seams can be a weak point in the backpack's water resistance if they are not sealed with a waterproof adhesive or tape.

In conclusion, while Kanken backpacks are designed to be water-repellent and can handle light rain and splashes, they are not fully waterproof and should not be relied upon to keep your belongings dry in heavy rain or when submerged in water. For activities where you expect to encounter a lot of water, it's recommended to look for backpacks that are specifically designed and tested for waterproofness, with sealed zippers and seams, and possibly even a waterproof lining.
